Figures
- fig 1.
A–C, Graphic depictions of mean (± SD) for brain volume (A), hippocampal volume (B), and VBR (C) for ϵ4+ and ϵ4− subjects for each diagnostic classification: control group, Alzheimer disease (AD), mild ambiguous (M/A), vascular dementia (VaD), cerebrovascular disease (CVA), frontal lobe dementia (FLA), Parkinson's disease (Parkinson), psychiatric disorder (Psych), dementia unknown (Dem Unk), alcoholism (ETOH), and amnesic disorder (Mem Amn). The first numeric value represents the total number of ϵ4− subjects, with the second numeric value indicating sample size of the ϵ4+ subjects
- fig 2.
A–C, Scatter plots for subjects with AD and combined MCI and VaD by age for brain volume (A), hippocampal volume (B), and VBR (C) based on the following correlations: Brain volume, rϵ4− = −.26, P ≤ .01; rϵ4+ = −0.19, P ≤ .01; hippocampal volume, rϵ4− = 0.17, P ≤ .05; rϵ4+ = 0.01, P > .05; and VBR, rϵ4− = −.34, P ≤ .01; rϵ4+ = 0.13, P ≤ .05
- fig 3.
A–C, Mean (± SD) for brain volume (A), hippocampal volume (B), and VBR (C) by length of disease (LOD) in years
- fig 4.
A–C, Mean (± SD) for brain volume (A), hippocampal volume (B), and VBR (C) for 3MS performance, which has been segregated into three levels: normal (> 91), mild to moderate impairment (71–90), and moderate to severe impairment (<70). Correlation values (Spearman rank) for each brain measure by 3MS performance level are shown in the boxes
